xHPTDC8-PCIe

Time-to-digital converter xHPTDC8-PCIe

Our most versatile TDC combines the precision of the xTDC4-PCIe with the channel count and flexibility of the HPTDC8-PCI.
The occurring cycle to cycle jitter of the xHPTDC8-PCIe is much lower than the bin size of 13ps. Therefore you can expect an RMS error below 7ps for your measurements.

High precision

The occurring cycle to cycle jitter of the xHPTDC8-PCIe is much lower than the bin size of 13ps. Therefore you can expect an RMS error below 7ps for your measurements.
The threshold discriminators can use positive or negative threshold with configurable voltage. This allows you to use the xHPTDC8-PCIe with a wide range of detectors, constant fraction discriminators (CFD) or signal standards in general.

Bipolar

The threshold discriminators can use positive or negative threshold with configurable voltage. This allows you to use the xHPTDC8-PCIe with a wide range of detectors, constant fraction discriminators (CFD) or signal standards in general.
All inputs can also be used to output periodic pulse patterns to control your experimental setup. The exact timing of these is measured by the TDC.

TiGer timing generator

All inputs can also be used to output periodic pulse patterns to control your experimental setup. The exact timing of these is measured by the TDC.
There is no limit to the acquired time interval with this TDC! It will output an infinite stream of timestamps for all incoming pulses. In case you prefer common start or common stop the device can output structured data that mimic these modes.

Versatile trigger windows

There is no limit to the acquired time interval with this TDC! It will output an infinite stream of timestamps for all incoming pulses. In case you prefer common start or common stop the device can output structured data that mimic these modes.
Measure the amplitude of a static analog input signal at defined time intervals or triggered by an external signal.

Voltage monitoring ADC

Measure the amplitude of a static analog input signal at defined time intervals or triggered by an external signal.
You can block inputs from being measured for a certain period of time relative to other input pulses. This reduces buffering requirements and CPU load.

Veto or gate inputs

You can block inputs from being measured for a certain period of time relative to other input pulses. This reduces buffering requirements and CPU load.

Don't restrict yourself to classic common start configurations! With the xHPTDC8-PCIe you can easily set up custom trigger scenarios. The device provides an infinite stream of timestamps - one for each input pulse. You may filter the stream in your own DAQ-software - or make use of the trigger and grouping features provided by xHPTDC8-PCIe.

Like the xTDC4-PCIe, the xHPTDC8-PCIe provides very high precision measurements with almost no cycle-to-cycle jitter. You can expect an RMS error very close to the quantization error. Its linearity is also practically perfect!

The inputs accept a wide range of single-ended signaling standards including NIM, TTL, and CMOS.

The PCIe bus master accesses directly a ring buffer in your PC memory, ensuring low CPU load at high data throughput.

Our TiGer timing generator allows you to create digital output pulse patterns on all connectors to control the timing of your experiment.

The newly added 18 bit ADC can monitor an analog voltage in your system in sync with the data acquisition or controlled by an external trigger.

Applications:

delay-line detectors

for microchannel plate detectors (MCP)
The position-readout of MCPs via a delay-line detector (DLD) is today’s best choice in the case of single-particle detection. Delay line detectors have excellent signal-to-noise properties, depict superior imaging dynamics, and, in addition, have a high time resolution. Modern delay-line detectors are furthermore multiple-hit-capable. Our TDCs are perfect companions for the readout of these detectors.

detectors for mass spectrometry

TOF- & MASS- spectroscopy detectors, TOFMS
In many TOFMS units cronologic TDCs are used to measure precisely the arrival of single ions. From the arrival time, the ion’s time-of-flight is deduced, from which the mass-to-charge ratio of the detected particle can be determined. A crucial factor for a successful measurement is the extremely low cycle-to-cycle jitter of our TDCs and their very low multiple hit detection deadtime.

low energy nuclear physics

LENP in nuclear astrophysics (NAP), cosmology and astronomy
While many aspects of nuclear physics are considered well understood after almost 100 years of research, several challenging questions are still open and under investigation. Our TDCs are used in gas detectors for nuclear physics experiments helping to understand the microcosm of the nucleus.

neutron detectors

Neutron detectors are not only used in the in area of radiation safety, e.g. in reactor instrumentation or special nuclear material (SNM) detection. They are as well employed in fusion plasma physics, particle physics, materials science, and even cosmic ray detection.

spectral imaging

spectral image acquisition, X-ray, radiology, photon-counting computed tomography, microscopy, hyperspectral imaging
The currently most advanced spectral imaging is based on photon-counting detectors. Such detectors typically require precise timing measurements and corresponding applications strongly benefit from fast data acquisition electronics. Already during the development of our products we focus on exactly these properties.
